This type of system replaces your existing "s-bend" pipe and exhaust canister. Two Brothers Racing s-bends are manufactured from .035" thin wall stainless steel, polished to a mirror finish. We use only #304 stainless which will never rust. After a few heat cycles the stainless steel turns a golden amber color which is the characteristic signature of high quality stainless steel.
Black Series Features:
These systems not only add horsepower but also drop significant weight from your bike. This type of canister can be mounted in the original canister position or in a "high" or "Low" mounted canister position depending on the bike and our available applications.

Two Brothers Racing M series exhaust canisters feature the highest level of quality construction and are designed to be fully serviceable in the event of damage, routine maintenance or the occasional repack. V.A.L.E.™ slip-on/full exhaust systems and flange-on systems feature CNC machined aluminum inlets and outlets. These special designs provide for ease of maintenance as well as simplified construction, which is what a premium performance product is all about! The exhaust note produced by all of Two Brothers Racing's Top Level exhaust systems is best described as being deep and throaty without suffering from the shrill whine normally associated with other manufacturer’s straight through muffler canisters.
V.A.L.E.™ Fitment (Variable Axis Locking Exhaust)
The V.A.L.E.™ system is Two Brothers Racing’s revolutionary and patent pending method of attaching our muffler canisters to the exhaust tube without the use of springs or welding. Two Brothers Racing V.A.L.E.™ systems allow the muffler assembly - exhaust tube and canister - to be positioned perfectly on the bike before all the mounting hardware is fully tightened. Once the canister and exhaust tubes are properly aligned, the V.A.L.E.™ assembly locks the muffler canister to the exhaust tube assuring a perfect, leak-free fit. This system is simple and easy to install, requiring nothing more than a 5mm hex wrench, which is included with every one of Two Brothers Racing's exhaust systems. The X-Lite™ ring is the next step in the evolution of V.A.L.E.™ technology. CNC milled from 6061-T6 aluminum, the design of Two Brothers Racing's X-Lite™ ring efficiently and elegantly removes all unnecessary material from the coupling. This reduces the weight of the part while still maintaining its structural integrity.
Strength from Within
Not all cores are created equal. At Two Brothers Racing mufflers are engineered from the core to the cap. We use a stainless steel wound, perforated and corrugated core on all Two Brothers Racing systems. Core diameter and length varies depending on model needs and the desired performance characteristics. Our Stainless Steel Spiral Core is lighter than traditional cores of the same material and even some of our competition’s titanium cores. The Spiral Wound process delivers a 2dB sound decrease, further enhancing our uniquely deep sound attenuation.
Note: All canister materials deliver equal performance with their own unique look.
We have been using Carbon Fiber in motorcycle mufflers since 1992. We are currently the only US Company to exclusively use Filament Wound Carbon Fiber (FWCF) on every carbon fiber muffler we sell. We draw on only the best high temperature resins, and utilize a proprietary lining system adopted from spacecraft, for additional heat resistance. Our FWCF is continuously wound over a precision machined mandrel for a 100% seamless bond. The FWCF tube is then cured in a high temperature autoclave oven for superior strength and heat resistance. These crucial elements meld to form a precision lightweight muffler that will perform as well as it looks.
By weight titanium is one of the world’s strongest readily available alloys, making it ideal for our M series mufflers. It is 45% lighter than steel with comparable strength, and twice as strong as aluminum while being only 60% heavier. That’s right titanium is HEAVIER than aluminum, but since it is twice as strong we are able to use very thin (.024”) material to construct our Titanium muffler. The result is a muffler that is about 8.3oz. lighter than our M or C series aluminum mufflers. Titanium has become an industry standard for motorcycle mufflers due to its durability, corrosion resistance, light weight, and factory look.
